Abstract
The method of thermal-mine working of an oil reservoir includes providing at least one injection gallery and a recovery gallery and drilling therefrom, respectively, injection and recovery wells. The formation is heated up by feeding a heat carrier into the injection wells, and oil with associated water thus evolved is withdrawn through the recovery wells. The associated water is separated from the oil and pumped into the oil-bearing formation, to assist in driving-out the oil. The recovered oil is conveyed to the ground surface through the mine workings. At least one auxiliary well is also drilled, to connect directly the recovery gallery and the injection gallery; and, a pipe line is mounted in this auxiliary well and spaced from the walls of the bore of the auxiliary well. Oil and associated water are separated directly within the recovery gallery. The associated water thus obtained is conveyed via the pipe line to the injection gallery, to be fed into the injection wells, while at the same time oil and associated water are recovered through the annular space between the pipe line and the walls of the auxiliary well.
